meeting, the specification of the number of shares voted by each of them or represented by proxy, and the final result of the voting.

Board shall be documented in a special minute book which shall be signed on each occasion by the directors who attended the meeting. Should any of them die or be unavailable for any reason to sign the corresponding minutes, a note shall be made
of such impediment at the end of the minutes. The minutes shall be deemed to be approved as of the moment they are signed by the aforementioned persons and the resolutions adopted therein may be put into effect immediately. In any event, the

without the need for a special power of attorney, even for those acts or contracts for which the law demands such authorization. This is without prejudice to the powers that correspond to the Corporations Chief Executive Officer.

Article 20 bis:In carrying out the powers set out in the preceding article, the Board shall act always within the limitations set by the
investment and financing policy approved by the ordinary shareholders meeting in accordance with Article 119 of Decree No. 3,500 of 1980 and its amendments.

Article 21:The duties of a director may not be delegated and shall be exercised collectively at a legally constituted meeting. The Board
may delegate part of its powers to managers, senior executives, assistant managers or legal counsels of the Corporation, to the Chairman, a director or a committee of directors and, for specially determined purposes, to other persons. The
Corporation shall maintain a public record indicating its Chairman, directors, managers, senior executives and liquidators, specifying the dates of the beginning and end of their appointments.

CHAPTER FOUR

Directors Committee

Article
22:While the Corporation meets the equity and concentration requirements established in Article 50 bis, or any successor or replacement provision, of Law 18,046, it shall be obliged to appoint at least one independent director and a
Directors Committee. This Committee shall be governed in its formation, membership, operation and powers by the provisions of said law and the rulings on this subject issued by the Superintendence of Securities and Insurance.

Article 23:Notwithstanding the provisions of the preceding article and while the Corporation is an issuer of securities duly
registered at the New York Stock Exchange (NYSE) or any other American national stock exchange, the formation, membership, functioning and powers of the Directors Committee shall also be governed, where not contrary to Chilean law, by the
obligatory provisions for the so-called Audit Committee in the Sarbanes-Oxley Act (SOX) of the United States of America and the rulings on this subject issued by the Securities and Exchange Commission (SEC) and the New York Stock
Exchange (NYSE), or the competent body or entity in accordance with the legislation of the United States of America. However, in case of an irreconcilable or irremediable conflict, disagreement or incompatibility between the provisions of Chilean
and American legislation for the Directors Committee and the Audit Committee, respectively, Chilean law shall prevail over foreign law, although the Board may call an extraordinary shareholders meeting to amend the by-laws should this be
necessary, and it shall have the broadest powers, acting within its powers, to resolve such conflict, disagreement or incompatibility should this be possible, by the creation of new committees and/or sub-committees, including by the delegation of
part of its powers in accordance with Article 40 of Law 18,046. The shareholders, directors and Board of the Corporation should ensure at all times that the agreements and policies adopted by it are compatible and harmonious with the provisions of
both legislations.

Article 24:The Directors Committee shall be composed of three members, the majority of whom shall be
independent according to the criteria and requirements established for this purpose in Article 50 bis of Law 18,046, both at the time of their appointment and throughout the whole period in which they serve as members of the Committee. However,
complementing the provisions of Article 23 above, as long as the Corporation is an issuer of securities duly registered on the NYSE or any other American national stock exchange, and in order to strictly comply with the legal and regulatory
requirements that this registration involves, all the members of the Directors Committee should also meet the criteria and requirements of independence prescribed for this purpose by the SOX, SEC and NYSE. Therefore, no director who has been
elected or appointed as a member of the Directors Committee may have any link, interest or dependence with the Corporation, whether economic, professional, commercial or of a lending nature, whatever the amount or type, nor receive, directly
or indirectly, any income, remuneration or compensation from the Corporation or any of its subsidiaries which is not by concept nor has as the sole and exclusive source the duties performed as a member of the Board, as a member of the
Directors Committee or as a member of any other committee or sub-committee of directors of the Corporation.

---

Article 25:The loss of independence, which according to the laws governing the Corporation
and these by-laws, affects a member of the Committee, shall lead to the subsequent inability of the respective director to perform his/her duties as a director or a member of the Directors Committee and therefore he/she should cease
automatically to serve in that position, without prejudice to his/her accountability to the shareholders.

Article 26:The directors
appointed as members of the Directors Committee shall remain as such for the period of their appointment as directors, and may only resign from this position when they resign as directors, or if they develop an incapacity to perform the
applicable duties, in which case the provisions of the preceding Article shall apply. No director elected or appointed as a member of the Directors Committee may be excused from this election or appointment.

Article 27:The meetings of the Directors Committee shall be validly constituted with the presence of an absolute majority of its
members and its resolutions shall be adopted by an absolute majority of the members present. The Directors Committee must elect a Chairman from among its members, who shall have the deciding vote in the event of a tied vote.

Article 28:The Committee shall have the powers and duties that have been expressly contemplated in both, the laws and their regulations
as well as the rules issued for this purpose by the competent administrative authority, especially those stated in Article 50 bis of Law 18,046, and any other matter, mandate, power or duty conferred on it by a shareholders or Board meeting.

Article29:The deliberations, agreements and organization of the Directors Committee shall
be governed, in all that may be applicable, by the regulations relating to Board meetings of the Corporation.
